Yes, like that padding. It is different on these particular x30 racks than on the zero flex but it's the same concept. If I am correct the zero flex has more of a thin rubber strip sort of in the rack arms that cushions but also keeps the boards from sliding, and these x30 racks have more of a foam cushion on top of the arms for padding because once you tighten the spring loaded arms the board shouldn't slide. I have never seen these x30 racks before. I think that McMaster website has something that will work though. I really appreciate the help man. Thanks.
